Solumina — Logic Puzzle

Solumina is a pure deduction game. Every puzzle has exactly one solution, and there's always a next step logic can prove — you never have to guess. The board is 6×6. You fill each cell with a sun or a moon, following three rules: • No symbol repeats three times in a row, horizontally or vertically • Every row and column has three suns and three moons • Marks between cells show matching (=) or different (×) pairs Simple to learn. What grows is how deep the reasoning goes. 500 HANDCRAFTED LEVELS Difficulty rises deliberately, introducing one deduction technique at a time. From the first board to the five-hundredth, none of them ask for luck. HINTS THAT TEACH Stuck? The hint doesn't hand you the answer. It shows the cell where a deduction is possible and explains the reasoning. You learn the technique instead of just moving on. 65 ACHIEVEMENTS Solve without hints. Solve without mistakes.
